Java Setter and Getter

Question

I am trying to get the GETTER of "FileHandler.java" to return the value(final_match) to "main.java" and out put. Problem is that final_match outputs as 0. In "FileHandler.java" Outside of my getter final_match has the correct value, but when called/returned from the GETTER value is plain 0

main.java

package textreader;

import java.io.File;
import java.util.ArrayList;
import java.util.Scanner;

public class main {

public String data = "";

public static void main(String[] args) {

    Scanner user_input = new Scanner(System.in);
    final File directory = new File("E:\\test\\filename.txt");
    //  final File directory2 = new File("E:\\test\\filename2.txt");
    ArrayList<File> f = new ArrayList<>();
    f.add(directory);
    //  f.add(directory2);
    final String words;

    System.out.println("The word you would like to search for. ");
    System.out.println("----------------------------------------");
    words = user_input.next();

    main aMain = new main(f, words);

}

main(ArrayList<File> f, String words) { //constructor 
    ArrayList<FileHandler> threadArray = new ArrayList<>();//arraylist of type filehandler
    for (File file : f) {
        FileHandler fh = new FileHandler(this, words, file);// instance of filehandler = fh
        threadArray.add(fh);
        fh.start();

        for (FileHandler x : threadArray) {
            if (x.isFinished()) {
                x.setFinished(true);
                synchronized (x) {
                    x.notify();// notify next thread to continue

                }
            }

            int answer = x.getfinal_match(); // CALLING THE GETTER FOR VALUE
            System.out.println("----------------------------------------");
            System.out.println("this word has appeared: " + answer + " times.");
            System.out.println("----------------------------------------");

        }
    }
}
}

            for (String List1 : List) {

//OUTPUT  
//run:  
//the word you would like to search for.

//----------------------------------------  
//this word has appeared: 0 times.

//EXPECTED OUTPUT  
//run:  
//The word you would like to search for.   
//----------------------------------------  
//dog  
//testing GETTER 123456 5  
//----------------------------------------
//this word has appeared: 5 times. (THIS IS THE MAIN VALUE THAT HAS TO CHANGE)  
//----------------------------------------  
//testing  5  
//BUILD SUCCESSFUL (total time: 2 seconds)  

Answer 1

Your final_match is 0 at the time of the output, since the thread starts and is not finished yet, when you output the value of final_match.
